+The trilogy integration traces any SQL command sent through the `trilogy` gem.
+
+```ruby
+require 'trilogy'
+require 'ddtrace'
+
+Datadog.configure do |c|
+  c.tracing.instrument :trilogy, **options
+end
+
+client = Trilogy.new(host: "localhost", username: "root")
+client.query("SELECT * FROM users WHERE group='x'")
+```
+
+`options` are the following keyword arguments:
